A new bicyclo[9.3.0]tetradecane diterpenoid (dolabellane) lactone named clavulactone (I) was isolated from soft coral qunzhuchong (Clavularia sp.). Its partial structure was determine by spectral anal. and hydrogenation reaction. X-ray anal. established the complete mol. structure of I and the relative configuration. Finally, according to the neg. Cotton effect of n畃* and CD band of a,b-unsatd. d-lactone at 252 nm, the absolute configuration was assigned.

Key words: LACTONES, X-RAY DIFFRACTION ANALYSIS, SPECTROGRAPHIC ANALYSIS, CIRCULAR DICHROISM, DITERPENES, ABSOLUTE CONFIGURATION, CLAVULARIA, ANTHOZOA
